Parthenogenesis in scorpions: some history - new data
Journal of Venomous Animals and Toxins including Tropical Diseases, 2008 Parthenogenesis, a rare phenomenon in Chelicerates, apart from mites, is reviewed in scorpions, notably Tityus serrulatus Lutz & Mello from Brazil, Tityus columbianus (Thorell) from Colombia and Tityus metuendus Pocock from Peru and Brazil.

Limited Mating Ability of a Wasp Strain with Rickettsia-Induced Thelytoky
Annals of the Entomological Society of America, 2020 Abstract Sexual reproduction is the dominant mode of reproduction in plants and animals; however, some species from various taxonomic groups reproduce asexually. Because some of these asexual species lack DNA recombination and so have low genetic variability, these asexual species are more likely to go extinct than sexual species ...

Restricted Gene Flow among Lineages of Thrips tabaci Supports Genetic Divergence Among Cryptic Species Groups. [PDF]
PLoS ONE, 2016 Knowledge of the relative influence of population- versus species-level genetic variation is important to understand patterns of phenotypic variation and ecological relationships that exist among and within morphologically indistinguishable cryptic ...

Detection of Gene Flow from Sexual to Asexual Lineages in Thrips tabaci (Thysanoptera: Thripidae). [PDF]
PLoS ONE, 2015 Populations of Thrips tabaci are known to have two sympatric but genetically isolated reproductive modes, arrhenotoky (sexual reproduction) and thelytoky (asexual reproduction).

Entomologia Experimentalis et Applicata, EarlyView.In this study we measured the impact of access to sugar and hosts on the longevity and fecundity of six Trichogramma species: T. cacoeciae, T. chilonis, T. minutum, T. leptoparameron, T. pintoi and T. sibericum. The impact of food differed among species, but there was a general tendency of increased life expectancy and potential fecundity with sugar ...

Molecular identification of Trichogramma egg parasitoids of Ostrinia nubilalis in northeastern Serbia [PDF]
Archives of Biological Sciences, 2018 The European corn borer Ostrinia nubilalis (Hubner, 1796) (Lepidoptera: Pyralidae) is a major pest of corn (Zea mays Linnaeus, 1753) in Serbia. Regular monitoring of O.

Journal of Applied Entomology, EarlyView.ABSTRACT Many species of Mesostigmata soil mites have potential as biological control agents of pests/parasites. This study evaluated the predation potential of two of these species, Gamasellodes lavafesii (Ascidae) and Cosmolaelaps mediocuspis (Laelapidae).

Diploid males support a two-step mechanism of endosymbiont-induced thelytoky in a parasitoid wasp [PDF]
BMC Evolutionary Biology, 2015 Haplodiploidy, where females develop from diploid, fertilized eggs and males from haploid, unfertilized eggs, is abundant in some insect lineages. Some species in these lineages reproduce by thelytoky that is caused by infection with endosymbionts: infected females lay haploid eggs that undergo diploidization and develop into females, while males are ...

Cytogenetics of a parthenogenetic Arctic species of Micropsectra (Diptera, Chironomidae)
Comparative Cytogenetics, 2011 Micropsectra sedna (Oliver, 1976) is a parthenogenetic midge from the Canadian Arctic. The parthenogenetic mechanism is apomictic thelytoky, with a restitutional division during oogenesis, as found in other parthenogenetic Chironomidae.
